Water purification made easy Intuitive to use, ergonomic handset design Clear water purity display for absolute confidence as you dispense Flexible dispensing in four different ways:
•
Realtime TOC monitoring for critical analytical applications
Variable flow – drop by drop or up to 2 liters per minute
•
Autovolume dispense from 50ml to 60 liters and repeat dispensing
• Hands free with optional foot pedal • Locked dispense for glassware filling
Prioritized information shown at all times (system status, TOC, alarm)
POU filters for multiple applications •
Remove endotoxins, DNase, RNase and bacteria
• Conforms to international water
standards e.g. CLSI, CLRW, ISO 3696: Grade 1,2,3, ASTM D1193-06, Pharmacopeia USP, EP and JP
Optional accessories
• Wall mounting bracket • Foot pedal • Thermal printer • Point of Use filters • Leak sensor
Designed for todayâ&#x20AC;&#x2122;s laboratories
Customized settings to suit your application
185nm/254nm UV lamp for low TOC water production needed for organic sensitive application
Easy-access for routine maintenance
Multiple dispense positioning, wall, bench, height adjustable arm, hand-held dispensing
Designed for simple easy installation
Purification pack quick and easy to replace
Data capture via USB for system performance validation
Quick and easy sanitization
Minimize microbial growth to give you absolute confidence in the water purity. The simple procedure involves one single sanitization pack so no harsh chemicals need to be ordered, handled or mixed. No additional consumables need to be replaced during this short process.
Global network, local support
Our highly trained service engineers will apply their expertise to the installation, validation and maintenance of your water purification system. We aim to provide a first-time-fix service.
